OV/Reminder

The architecture of OV/Reminder comprises several key components designed for efficient email scheduling within a z/OS environment. The core components include the scheduler, the message processor, and the email transmitter. The scheduler is responsible for managing the timing of email transmissions, using configuration files to determine when emails should be sent.

The message processor formats and prepares the email content, pulling data from various sources as needed. The email transmitter uses SMTP to send the messages to the specified recipients. Communication between components is typically handled through internal system calls and file I/O operations.

The system utilizes configuration files to store settings such as SMTP server details, email templates, and scheduling parameters. These files are typically text-based and can be edited to customize the behavior of the system. The system interacts with the z/OS operating system for resource management and security.

Network requirements include access to an SMTP server, typically on port 25 or 587. The system leverages the z/OS security infrastructure, such as RACF, for user authentication and access control. Logging capabilities are provided to track email transmissions, errors, and system events, which can be used for auditing and troubleshooting.
